Phoenix Contact vulnerabilities and threats

An authenticated attacker with low privileges can access an endpoint in the controller’s web interface that is vulnerable to SQL injection. The vulnerability affects a SQLite database used only for storing notification messages. Therefore, the impact is limited to the system’s notification functionality.

An unauthenticated denial-of-service vulnerability in the device's PLCnext Engineer communication interface allow an remote attacker to interrupt access via the client application. Successful exploitation prevents communication until the PLCnext service is manually restarted.

The device's PROFINET service is affected by a buffer overflow vulnerability that exists in the default configuration. An unauthenticated remote attacker could exploit this vulnerability to reboot the device or execute arbitrary code.

CVE-2026-7849 is a critical command injection vulnerability in Phoenix Contact's CHARX SEC-3150 device. An unauthenticated remote attacker can inject commands into the system configuration, which are executed with root privileges. This flaw affects versions 1.0.0 up to but not including 1.9.1. The issue is fixed in version 1.9.1.

Due to a flaw in the execution order of scripts during shutdown, the firewall is terminated prematurely during system shutdown. This creates a temporary window in which internal services may become externally accessible, potentially allowing an unauthenticated remote attacker to connect to these services, resulting in full system compromise.

A reboot of the charging controller can be triggered via Modbus TCP without authentication. Therefore, when the Modbus functionality is enabled by opening the port that CharxModbusServer is listening, an unauthenticated attacker can perform a Denial-of-Service attack.

CVE-2026-44105 is a vulnerability in Phoenix Contact CHARX SEC-3150 devices where credentials for the local user "user-app" are inserted into log files. This exposure allows a low-privileged local attacker with access to these logs to authenticate via SSH as the limited user "user-app", potentially disrupting charging operations.

A privilege escalation vulnerability in the init-script for user-applications allows a low-privileged local user to execute arbitrary commands as root, resulting in full system compromise.

The firmware update process for the basemodule of the charging controller only validates the CRC32 checksum without cryptographic signature verification. This allows an unauthenticated remote attacker to install a modified firmware, resulting in full system compromise.

An unauthenticated remote attacker can inject malicious firmware into the internal charging module because the JupiCore service transmits firmware updates without performing integrity or verification check. Successful exploitation may compromise the integrity of the affected device. This vulnerability could be used in chain with CVE-2026-44104.

An unauthenticated remote attacker can trigger a firmware update download via the OCPP backend by supplying an invalid firmware file. This will cause the file to remain accessible for a short period before it is deleted due to improper locking during the cleanup process.

Due to missing authentication the CHARX OCPP Agent service allows an unauthenticated remote attacker to reconfigure the backend connection. This can lead to Denial-of-Service and confidential data being disclosed to the attacker.

The CHARX JupiCore service allows an unauthenticated remote attacker to reconfigure charging points. This can lead to disclosure of charging point UIDs, Denial-of-Service and files tampering.

A privilege escalation vulnerability in the system configuration allows a low-privileged local user to execute arbitrary commands as root, resulting in full system compromise.

This vulnerability allows an unauthenticated remote attacker with control over the OCPP backend via firewall-bypass to perform an OS command injection, resulting in the execution of arbitrary commands as the limited user charx-oa. Charging could be interrupted.

CVE-2026-44097 is a vulnerability in Phoenix Contact CHARX SEC-3150 that allows a low-privileged remote attacker with operator access to upload arbitrary files via the REST endpoint used for firmware updates. This can lead to persistent storage of attacker-controlled files and may exhaust device resources, potentially causing a denial-of-service condition.

A privilege escalation vulnerability in udhcpc allows a local user "charx-web" to execute arbitrary commands as root, resulting in full system compromise.

A privilege escalation vulnerability in a script used for network configuration allows a low-privileged local user to execute arbitrary commands as root, resulting in full system compromise.

An unauthenticated remote attacker can enforce the system to fall back to a firmware partition with an insecure configuration including default credentials. This could allow the attacker to gain SSH access to the system as an unprivileged user "user-app". Charging could be interrupted.

A local privilege escalation vulnerability in the init-script for user-applications allows a low-privileged local user to execute arbitrary commands as root, resulting in full system compromise.
